This syncs drivers/ddr/marvell/a38x/ with the master branch of repository https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git up to the commit 7c351731d196 ("Merge pull request #29 from pali/sync-a38x-uboot"). This patch was created by following steps: 1. Replace all a38x files in U-Boot tree by files from upstream github Marvell mv-ddr-marvell repository. 2. Run following command to omit portions not relevant for a38x and ddr3: files=drivers/ddr/marvell/a38x/* sed 's/#if defined(CONFIG_ARMADA_38X) || defined(CONFIG_ARMADA_39X)/#ifdef TRUE/' -i $files unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 -UCONFIG_APN806 \ -UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \ -UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \ -UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DTRUE $files 3. Manually omit SPDX-License-Identifier changes from this patch as upstream license in upstream github repository contains long license texts and U-Boot is using just SPDX-License-Identifier. After applying this patch, a38x ddr3 code in upstream Marvell github repository and in U-Boot would be fully identical. So in future applying above steps could be used to sync code again. The only change in this patch is removal of dead code and some fixes with include files.

|
* Training search & read result routine
|
|
* This function implements the search algorithm
|
|
* first it calls the function ddr3_tip_ip_training_wrapper_int which triggers the search from l2h and h2l
|
|
* this function handles rx and tx search cases
|
|
* in case of rx it only triggers the search (l2h and h2l)
|
|
* in case of tx there are 3 optional algorithm phases:
|
|
* phase 1:
|
|
* it first triggers the search and handles the results as following (phase 1):
|
|
* each bit, which defined by the search two edges (e1 or VW_L and e2 or VW_H), match on of cases:
|
|
* 1. BIT_LOW_UI 0 =< VW =< 31 in case of jitter use: VW_L <= 31, VW_H <= 31
|
|
* 2. BIT_HIGH_UI 32 =< VW =< 63 in case of jitter use: VW_L >= 32, VW_H >= 32
|
|
* 3. BIT_SPLIT_IN VW_L <= 31 & VW_H >= 32
|
|
* 4. BIT_SPLIT_OUT* VW_H < 32 & VW_L > 32
|
|
* note: the VW units is adll taps
|
|
* phase 2:
|
|
* only bit case BIT_SPLIT_OUT requires another search (phase 2) from the middle range in two directions h2l and l2h
|
|
* because only this case is not locked by the search engine in the first search trigger (phase 1).
|
|
* phase 3:
|
|
* each subphy is categorized according to its bits definition.
|
|
* the sub-phy cases are as follows:
|
|
* 1.BYTE_NOT_DEFINED the byte has not yet been categorized
|
|
* 2.BYTE_HOMOGENEOUS_LOW 0 =< VW =< 31
|
|
* 3.BYTE_HOMOGENEOUS_HIGH 32 =< VW =< 63
|
|
* 4.BYTE_HOMOGENEOUS_SPLIT_IN VW_L <= 31 & VW_H >= 32
|
|
* or the center of all bits in the byte =< 31
|
|
* 5.BYTE_HOMOGENEOUS_SPLIT_OUT VW_H < 32 & VW_L > 32
|
|
* 6.BYTE_SPLIT_OUT_MIX at least one bits is in split out state and one bit is in other
|
|
* or the center of all bits in the byte => 32
|
|
* after the two phases above a center valid window for each subphy is calculated accordingly:
|
|
* center valid window = maximum center of all bits in the subphy - minimum center of all bits in the subphy.
|
|
* now decisions are made in each subphy as following:
|
|
* all subphys which are homogeneous remains as is
|
|
* all subphys which are homogeneous low | homogeneous high and the subphy center valid window is less than 32
|
|
* mark this subphy as homogeneous split in.
|
|
* now the bits in the bytes which are BYTE_SPLIT_OUT_MIX needed to be reorganized and handles as following
|
|
* all bits which are BIT_LOW_UI will be added with 64 adll,
|
|
* this will hopefully ensures that all the bits in the sub phy can be sampled by the dqs
